Creating your own Strawberry Crumble Cake is simple! Follow these easy steps for the perfect result:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan.
2. Prepare the Strawberries: In a mixing bowl, combine sliced strawberries with lemon juice and set aside.
3. Mix Dry Ingredients: In a large bowl, sift together the flour, granulated sugar, baking powder, salt, and optional cinnamon.
4. Cream Butter and Sugar: In another bowl, cream together the softened butter and brown sugar until light and fluffy.
5. Combine Wet Ingredients: Add the egg, milk, and vanilla to the butter-sugar mixture, mixing until smooth.
6. Blend Ingredients: Gradually add the dry ingredients to the wet mixture, stirring just until combined. Do not overmix.
7. Add Strawberries: Fold in the prepared strawberries gently, ensuring they’re evenly distributed.
8. Prepare the Crumble: In a separate bowl, mix together 1/2 cup flour, 1/4 cup brown sugar, and 1/4 cup cold butter to create a crumbly topping.
9. Assemble in the Pan: Pour the batter into the greased cake pan. Sprinkle the crumble mixture evenly over the top.
10. Bake: Place the pan in the preheated oven and bake for 45-50 minutes, or until a toothpick inserted in the center comes out clean.
11. Cool: Remove the cake from the oven and let it cool in the pan for about 15-20 minutes before transferring to a wire rack.
